1 Claim. (o1. 15s- 2s This invention relates to improvements in oil burners, and more particularly to an oil burner tube assembly.

Anobject of the invention is to provide an improved oil burner tube assembly having a tube formed with a flared forward end adapted to receive a cone flame spreader, and an air deflector mounted in said tube at a point well back from the cone, together with an oil pipe line extending through the air deflector and terminating in an adapter supporting spaced nozzles, and a spark tip, said spark tip being positioned above the nozzles outside of the oil spray and consequently the flame pattern.

Another object of the invention is to provide an improved oil burner tube assembly including a tube formed with a flared forward end adapted to receive a cone flame spreader, and an air deflector mounted in said tube at a point spaced back from said cone, together With an oil pipe line extending through the air deflector and terminating in an adapter supporting spaced nozzles and a spark tip, also there is provided a spark plug supported by said oil pipe line having an electrode adjacent said spark tip.

A further object of the invention is to provide an improved oil burner tube assembly which will be highly eflicient in operation, and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application,

Like characters of reference are used through the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided an oil burner generally denoted by the reference numeral 9, and supporting an oil burner tube 2 being outwardly flared at 3 at its outer end.

An air deflector blade or member 3 is positioned in the tube 2 well back from its forward or outer end, and comprises the four angularly disposed blades each formed with the forwardly extending flange or shoulder 5. One blade 5 is apertured at i to permit the spark plug 8 to extend therethrough, and is also formed with the central hub portion 9 through which the central aperture it is formed. The oil pipe or supply line ll from a source of oil supply (not shown) extends through the central aperture I0 and the air deflector 4, and is adapted to receive the adapter member or housing l2 on its forward end.

The adapter l2 comprises an annular portion l3 which is internally threaded as at M to screw on the end of said oil pipe line II. The annular portion is of the adapter I2 is formed with a forwardly extending housing l5 which is substantially rectangular in shape but provided with rounded corners it. A pair of spaced screwthreaded bores ii and is are formed in the forward portion of the housing l5, and communicate with the oil chamber H3 in the inner end of said housing l5.

The burner nozzles 29 are adapted to thread into the threaded bores El and 18 in the adapter, and a threaded opening 21 is formed in the upper portion or face of the adapter, to receive the threaded spark tip 22 which will extend above the burner nozzles 26 and a short distance in front of the same.

The spark plug 8 is provided with an insulated body, and includes a terminal 23 at its rear end, and an elongated spark point or electrode 24 at its forward end which is bent to extend to, and lie a short distance above and in front of the spark tip 22.

The double clamp support comprising a closed ring 25 and an adjoining split ring 26, is positioned respectively over the oil line H and spark plug 8. The set screw or bolt 21 is extended through the ring 25 to clamp the same on the oil line H, while a threaded screw or stove bolt 28 extends between the ends of the split ring 26 to support the spark plug 8 therein. A wire from a suitable coil or transformer (not shown) will be attached to the terminal end 23 of the spark plug 8.

A cone flame spreader 28 is adapted to be positioned in the flared forward end of the burner tube 2, and is provided with an enlarged annular positioning flange 29 about its forward edge. The inner wall of the flame spreader 28 is dished out as at 30, and a plurality of short angularly disposed flame spreading bafiles 3| are secured to said inner wall and extend at an angle to the periphery of the spreader, and also at an angle to the inner Wall thereof, as clearly shown in Figures 2 and 3 of the drawings.

It will be noted that the spark points are above the flame or oil spray cone, and hence cannot be fouled, thus insuring an immediate ignition of the oil when the burner is turned on.

Provision has been made to replace the spark points if needed at any time.

While the preferred embodiment of the invention has been illustrated and described, it will be understood that it is not intended to limitithe scope of the invention thereto, as many minor changes in construction may be resorted't'o without departure from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to securebyLetters Patent in the United States is:

An oil burner assembly comprising a burner tube having a flared forward end, a cone flame spreader positioned in the forward end of said tube, an air deflector in said tube, an oil feed line disposed centrally and longitudinallyin said tube, a T-shaped outlet adapter connected to the 'end of said oil feed line between said air-deflector and said cone spreader, spaced burner nozzles re- REFERENCES CITED The following references are of record in the file'of this patent:
